"Load recognised as non-dimmable" with Walli Dimmer





I have a Fibaro Walli Dimmer with number of dimmable LEDs, which work perfectly in another place of the house with the  same type of dimmer, but for some reason the auto-calibration recognises the load as non-dimmable. Regardless of what I do, adding bypass and forcing calibration again, overwriting the auto-calibration with "ON/OFF mode disabled (dimming is possible), nothing seems to trigger dimming for them. While the auto-calibration is performed, the LEDs are dimming perfectly visually but at the end of the process the result  is "load recognised as non-dimmable".


Interesting to mention that dimming did work once for them, at the very beginning (quite smooth), then I've forced auto-calibration by accident and nothing seems to get the dimming back.


I've got a 3 wire setup, with Fibaro Bypass 2, LEDs are 4 x 10W with dimmable TRIAC driver (trailing edge).


Any help is highly appreciated.

  • I made more than enough attemps to get it back where it was but no luck.


    Just wondering, would the dimming work if I calibrate the dimmer on the LEDs where it works, and then just move it to where it doesn't?


    Does the dimmer stores more parameters then seen in the web ui as result of the calibration? Is there a way to download/upload these settings from one dimmer to another?

  • Ok, in case anybody faces same issue - just run auto-calibration where it works, and then move the dimmer to the spot where it doesn't. And don't run auto-calibration ever again.
